TECHNICAL FIELD

The present invention relates to the field of pharmaceutical technology and describes a novel advantageous preparation for an active ingredient. The novel preparation is suitable for the production of a large number of pharmaceutical dosage forms.

BACKGROUND ART

In order to achieve particular properties of a dosage form, such as, for example, taste masking in the case of active ingredients with an unpleasant taste, resistance to gastric juice in the case of acid-labile active ingredients or controlled release of an active ingredient, normally active ingredient pellets are provided with an appropriate functional coating. If such coated pellets are then further processed to dosage forms, for example shaped to tablets by compression with excipients, there is a risk that the coating is damaged and thus the functionality is at least partly lost again.

DESCRIPTION OF THE INVENTION

It is an object of the present invention to provide a preparation for active ingredients which is able to retain a desired functionality and can be further processed to a large number of pharmaceutical process forms with negligible impairment of a given functionality.

It has now been found, surprisingly, that this object is achieved by a preparation in which an active ingredient is essentially uniformly dispersed in an excipient matrix composed of one or more excipients selected from the group of fatty alcohol, triglyceride, partial glyceride and fatty acid ester.

The invention therefore relates to a preparation in which an active ingredient is essentially uniformly dispersed in an excipient matrix composed of one or more excipients selected from the group of fatty alcohol, triglyceride, partial glyceride and fatty acid ester.

It has further been found that particularly advantageous preparations can be obtained by adding solid paraffin to the excipient matrix. The invention therefore relates further to a preparation in which an active ingredient is essentially uniformly dispersed in an excipient matrix composed of at least one solid paraffin together with one or more excipients selected from the group of fatty alcohol, triglyceride, partial glyceride and fatty acid ester.

The invention further relates to preparations in which an active ingredient is essentially uniformly dispersed i) in an excipient matrix composed of a mixture comprising at least one fatty alcohol and at least one solid paraffin, ii) in an excipient matrix comprised of a mixture comprising at least one triglyceride and at least one solid paraffin, iii) in an excipient matrix composed of a mixture comprising at least one partial glyceride and at least one solid paraffin or iv) in an excipient matrix composed of a mixture comprising at least one fatty acid ester and at least one solid paraffin.

Further subject matters are evident from the claims.

The preparations for the purpose of the invention preferably comprise numerous individual units in which at least one active ingredient particle, preferably a large number of active ingredient particles, is present in an excipient matrix composed of the excipients of the invention (also referred to as active ingredient units hereinafter). The active ingredient is preferably essentially uniformly dispersed, in particular homogeneously dispersed or dissolved, in the excipient matrix. A preparation preferably comprises microspheres.

The preparations of the invention are distinguished in particular by high stability, a release of active ingredient which can be controlled by the particle size and composition of the matrix, good flow characteristics, good compressibility and by a uniform delivery of active ingredient. In the case of acid-labile active ingredients it is moreover possible to achieve, through choice of the matrix excipients, an acid resistance so that it is possible in the case of oral forms to dispense with an acid-resistant coating (enteric coating). In the case of active ingredients which have an unpleasant taste or, for example, show a local anesthetic effect in the mouth after administration, it has been observed that an unpleasant taste of the active ingredient can be masked, and anesthetic effects in the mouth can be avoided, by preparations of the invention. It is particularly worthy of mention that the preparations of the invention can be further processed to a large number of pharmaceutical dosage forms without thereby losing a given functionality (such as taste masking, resistance to gastric juice, slowing of release). Thus, for example, on compression of the active ingredient units of the invention no or negligible loss of functionality is observed even if deformation of the active ingredient units occurs. In contrast to this, with conventional pellets, which normally have a functional coating (such as taste masking, resistance to gastric juice, slowing of release), a certain degree of damage to the coating and thus to the functionality is observed on further processing to dosage forms, for example on compression to tablets. This may also lead in some cases to active ingredient being released in an unwanted way.

The particle size of the individual units is advantageously less than or equal to 2 mm, preferably 50-800 μm, particularly preferably 50-700 μm and very particularly preferably 50-600 μm. Preference is given to microspheres of a particle size of 50-500 μm, particularly preferably of 50-400 μm. Particular preference is given to monomodal microspheres with a particle size of 50-400 μm, particularly of 50-200 μm.

The matrix of the of the invention is also outstandingly suitable as dosage form for active ingredients from the class of substances known as acid-labile H⁺, K⁺-ATPase inhibitors, which are also referred to as irreversible proton pump inhibitors. Acid-labile proton pump inhibitors (H⁺/K⁺-ATPase inhibitors) which may be particularly mentioned for the purpose of the present invention are substituted pyridin-2-ylmethylsulfinyl-1H-benzimidazoles as disclosed, for example, in EP-A-0 005 129, EP-A-0 166 287, EP-A 0 174 726, EP-A-0 184 322, EP-A-0 261 478 and EP-A-0 268 956. Those which may be mentioned as preferred in this conenction are 5-methoxy-2-[(4-methoxy-3,5-dimethyl-2-pyridinyl)-methylsulfinyl]-1H-benzimidazole (INN: omeprazole), 5-difluoromethoxy-2-[(3,4-dimethoxy-2-pyridinyl)-methylsulfinyl]-1H-benzimidazole (INN: pantoprazole), 2-[3-methyl-4-(2,2,2-trifluoroethoxy)-2-pyridinyl)methylsulfinyl]-1H-benzimidazole (INN: lansoprazole) and 2-{[4-(3-methoxypropoxy)-3-methylpyridin-2-yl]methylsulfinyl}-1H-benzimidazole (INN: rabeprazole). Further acid-labile proton pump inhibitors, for example substituted phenylmethylsulfinyl-1H-benzimidazoles, cycloheptapyridin-9-ylsulfinyl-1H-benzimidazoles or pyridin-2-ylmethylsulfinylthienoimidazoles, are disclosed in DE-A-35 31 487, EP-A-0 434 999 and EP-A-0 234 485 respectively. Examples which may be mentioned are 2-[2-(N-isobutyl-N-methylamino)benzylsulfinyl]benzimidazole (INN: leminoprazole) and 2-(4-methoxy-6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-9-ylsulfinyl)-1H-benzimidazole (INN: nepaprazole). The acid-labile proton pump inhibitors are chiral compounds. The term acid-labile proton pump inhibitor also encompasses the pure enantiomers of the acid-labile proton pump inhibitors and their mixtures in any mixing ratio. Pure enantiomers which may be mentioned by way of example are 5-methoxy-2-[(S)-[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole (INN: esomeprazole) and (−)-pantoprazole. The acid-labile proton pump inhibitors are moreover present as such or, preferably, in the form of their salts with bases. Examples of salts with bases which may be mentioned are sodium, potassium, magnesium or calcium salts. If the acid-labile proton pump inhibitors are isolated in crystalline form, they may contain variable amounts of solvent. The term acid-labile proton pump inhibitor therefore also represents according to the invention all solvates, in particular all hydrates, of the acid-labile proton pump inhibitors and their salts. Such a hydrate of the salt of an acid-labile proton pump inhibitor with a base is disclosed, for example, in WO91/19710. Acid-labile proton pump inhibitors which may be mentioned as particularly preferred are pantoprazole sodium sesquihydrate (=pantoprazole sodium×1.5 H₂O), (−)-pantoprazole sodium sesquihydrate, pantoprazole magnesium dihydrate, omeprazole magnesium, omeprazole and esomeprazole.

In another preferred embodiment of the invention, the active ingredient is a glucocorticosteroid, in particular ciclesonide.

The active ingredients may, depending on the nature of the active ingredient, also be present in the preparations of the invention in the form of a salt of the active ingredient. Particular mention may be made of the pharmacologically suitable salts of the inorganic and organic acids normally used in pharmaceutical technology. Suitable as such are, on the one hand, water-soluble and water-insoluble acid addition salts with acids such as, for example, hydrochloric acid, hydrobromic acid, phosphoric acid, nitric acid, sulfuric acid, acetic acid, citric acid, D-gluconic acid, benzoic acid, 2-(4-hydroxybenzoyl)-benzoic acid, butyric acid, sulfosalicylic acid, maleic acid, lauric acid, malic acid, fumaric acid, succinic acid, oxalic acid, tartaric acid, embonic acid, stearic acid, toluene sulfonic acid, methanesulfonic acid or 3-hydroxy-2-naphthoic acid, the acids being employed for preparing the salts in the equimolar ratio of amounts, or a ratio differing therefrom,—depending on whether the acid is monobasic or polybasic and depending on which salt is required.

On the other hand, salts with bases are also suitable. Examples of salts with bases which may be mentioned are alkali metal (lithium, sodium, potassium) or calcium, aluminum, magnesium, titanium, ammonium, meglumine or guanidinium salts, the bases being employed for preparing the salts also in the equimolar ratio of amounts or in a ratio differing therefrom.

The skilled worker is aware that active ingredients and their salts may, if they are isolated, for example, in crystalline form, contain various amounts of solvents. The active ingredients will therefore also be present in the preparations of the invention in the form of solvates and, in particular, hydrates, and in the form of solvates and, in particular, also hydrates of the salts of the active ingredients.

The active ingredients may also be chiral compounds. It is therefore also possible for the pure enantiomers of the active ingredients and mixtures thereof in any mixing ratio to be present in the preparations of the invention.

The fatty alcohol is preferably a linear, saturated or unsaturated primary alcohol with 10-30 carbon atoms. It is preferably a primary alcohol with 10 to 18 carbon atoms in linear chains. Examples of fatty alcohols which may be mentioned are cetyl alcohol, myristyl alcohol, lauryl alcohol or stearyl alcohol, with preference for cetyl alcohol. It is also possible if desired for mixtures of fatty alcohols to be present.

The triglyceride is glycerol with its three hydroxyl groups esterified by carboxylic acids. The carboxylic acids are preferably monobasic carboxylic acids with 8 to 22 carbon atoms, preferably naturally occurring carboxylic acids. It is possible in this case for the carboxylic acids to be different or, preferably, identical. Examples which may be mentioned are tristearate, tripalmitate and, particularly preferably, trimyristate (these triglycerides are commercially available under the name Dynasan 118, 116 and 114 respectively). It is also possible if desired for mixtures of triglycerides to be present.

The fatty acid ester is the ester of an alcohol with a fatty acid. The alcohol in this case is preferably a linear, saturated or unsaturated primary alcohol with 10-30, preferably with 12 to 18, carbon atoms. The fatty acid is preferably a monobasic carboxylic acid with 8 to 22, in particular 12 to 18, carbon atoms, preferably a naturally occurring carboxylic acid. Fatty acid esters preferred according to the invention have a melting point above 30° C. Examples of fatty acid esters which may be mentioned are cetyl palmitate, which is commercially available for example under the name Cutina® CP. It is also possible if desired for mixtures of fatty acid esters to be present.

The solid paraffin is preferably paraffinum solidum (ceresin). It is also possible alternatively to use ozokerite, for example. It is also possible if desired to use mixtures.

It is also possible if desired for mixtures of partial glycerides to be present.

If desired, the mixtures in the individual active ingredient units may include one or more other pharmaceutically suitable excipients. Other suitable excipients which may be mentioned by way of example are polymers, sterols and—in the case of acid-labile active ingredients—basic compounds.

The polymer is preferably povidone or ethylcellulose. It is also possible if desired for mixtures of polymers to be present. It is possible by adding suitable polymers, for example, to influence the pharmaceutical properties of the individual active ingredient units (e.g. delivery of the active ingredient). Particularly preferred polymers according to the invention are povidone or ethylcellulose.

Stearylamine and sodium stearate may be mentioned as preferred. The addition of basic compounds to the mixtures in the individual units results, in the case of acid-labile active ingredients, in particularly stable preparations and prevents possible discolorations.

The individual active ingredient units can be produced for example by spray drying or, preferably, by spray solidification, in particular also by spray prilling. Production is particularly preferably by prilling, in particular by vibration prilling.

For the spray solidification or prilling expediently the matrix excipients are liquefied to give a melt. The active ingredient is dissolved or dispersed in this solution, and the resulting solution or dispersion is sprayed or, preferably, prilled in a suitable apparatus. A dispersion of the active ingredient in a melt of the excipients is preferably used.

Spray solidification takes place in a manner known per se. A detailed description of this technique is to be found in P. B. Deasy, Microencapsulation and Related Drug Processes (1984).

The individual active ingredient units are particularly preferably produced by solidification from liquid phase by generating drops by means of vibrating nozzles and by solidifying the drops which are formed, after they have stabilized, by drying or cooling in a suitable medium (preferably gaseous or liquid). The suitable medium may be, for example, cooled gas such as air or nitrogen. Processes of this type and corresponding apparatuses are disclosed in DE 27 25 924, EP 0 467 221, WO99/33555 and WO00/24382.

It is particularly preferred according to the invention in the prilling process for the liquid phase flowing to the nozzle to be kept at a constant temperature. The solidification preferably takes place by instantaneous cooling in a suitable cooling medium. In prilling, moreover, it is preferred for the liquid phase flowing to the nozzle, the vibrating nozzle and the drops formed by prilling to be kept at a constant temperature until their spherical shape has stabilized, and for the solidification of the drops after their stabilization to be carried out instantaneously by cooling with a gaseous or liquid cooling medium. Systems suitable for prilling by means of vibrating nozzles are marketed, for example, by Brace GmbH, Aizenau, Germany. It is possible by means of prilling using vibrating nozzles to obtain the individual active ingredient units in the form of microspheres with a narrow monomodal particle size spectrum in the particle size range from 50 μm to 2 mm. The narrow monomodal particle size spectrum and the uniform spherical shape of the microspheres obtained in this way are expected to result in a uniformly smooth surface, a uniform, defined delivery of active ingredient and, in relation to passage through the stomach in the case of oral dosage forms (owing to the small particles), a behavior like that of a solution. The microspheres of the invention are distinguished in particular by high stability, a release of active ingredient which can be controlled via the particle size and composition of the matrix, good flow characteristics, good compressibility and a uniform delivery of active ingredient. It is particularly worthy of mention that the microspheres can be further processed to a large number of pharmaceutical dosage forms without thereby losing a given functionality (such as taste masking, resistance to gastric juice, slowing of release).

The microspheres are preferably monomodal microspheres with a particle size range of 50-800 μm, preferably 50-500 μm, particularly preferably 50-400 μm, in particular 50-200 μm.

The particle size of the active ingredient employed in the spray drying or spray solidification, prilling or vibration prilling is advantageously less than or equal to 100 μm, in particular less than 40 μm. The particle size is preferably in the range 1-20 μm, particularly preferably in the range 3-15 μm. Such a particle size can be achieved, for example, by grinding the active ingredient in a suitable mill.

The individual active ingredient units (preparations) of the invention can then be used as basis for producing the dosage forms of the invention. Examples which may be mentioned are dosage forms of the invention, to which the preparations can be processed, as suspensions, gels, tablets, coated tablets, multicomponent tablets, effervescent tablets, rapidly disintegrating tablets, powders in sachets, coated tablets, capsules, solutions or else suppositories. Preferred dosage forms in this connection are oral dosage forms, in particular tablets. Particular preference is given to rapidly disintegrating tablets and effervescent tablets. The excipients suitable for the desired dosage forms are familiar to the skilled worker on the basis of his expert knowledge. In the case of oral dosage forms it is surprisingly possible to dispense with the enteric coating.

In the case of rapidly disintegrating tablets, suitable excipients are, in particular, those excipients which on oral intake of the tablet bring about rapid disintegration of the tablets. Excipents which on oral intake of the tablet bring about rapid disintegration of the tablet preferably comprise one or more substances selected from the group of fillers and disintegrants. One or more other excipients from the group of lubricants, flavors, flavoring substances and surface-active substances are preferably present in the rapidly disintegrating dosage form of the invention. Binders can also be present if desired. The rapidly disintegrating dosage form particularly preferably comprises a mixture of at least one filler, one disintegrant and one lubricant. Fillers suitable according to the invention are, in particular, basic fillers such as calcium carbonate (e.g. MagGran® CC or Destab® 95) and sodium carbonate, sugar alcohols such as mannitol (e.g. Pearlitol® or Parteck® M), sorbitol (e.g. Karion®), xylitol or maltitol, starches such as corn starch, potato starch and wheat starch, microcrystalline cellulose, saccharides such as glucose, lactose, levulose, sucrose and dextrose. In a preferred development of the invention, the rapidly disintegrating dosage form of the invention comprises as filler a mixture of a basic filler (in particular calcium carbonate) and a sugar alcohol (in particular sorbitol or mannitol). Disintegrants suitable according to the invention are, in particular, insoluble polyvinylpyrrolidone (insoluble PVP, crospovidone), sodium carboxymethylstarch, sodium carboxymethylcellulose, alginic acid and starches able to carry out the function of a disintegrant (e.g. Starch 1500). Suitable lubricants which may be mentioned are sodium stearyl fumarate, magnesium stearate, calcium stearate, stearic acid, talc and highly disperse silica (Aerosil). Suitable surface-active substances which may be mentioned are sodium lauryl sulfate or Tween® 20, 60 or 80. Binders suitable according to the invention are polyvinylpyrrolidone (PVP, Polyvidon® K25, 90) or mixtures of PVP with polyvinyl acetate (e.g. Kollidon® 64), gelatin, corn starch mucilage, preswollen starches (Starch 1500), hydroxypropylmethylcellulose (HPMC) or hydroxypropylcellulose (L-HPC).

The proportion (in percent by weight based on the finished tablet) of filler in the rapidly disintegrating tablet is advantageously from 1 to 99% by weight. The proportion of filler is preferably from 30 to 95% by weight, and the proportion is very particularly preferably from 60 to 85% by weight.

The proportion (in percent by weight based on the finished tablet) of disintegrant in the rapidly disintegrating tablet is usually from 1 to 30% by weight. The proportion of disintegrant is preferably from 2 to 15% by weight. The proportion of disintegrant is particularly preferably from 5 to 10% by weight.

The proportion (in percent by weight based on the finished tablet) of lubricant in the rapidly disintegrating tablet is usually from 0.1 to 5% by weight. The proportion of lubricant is preferably from 0.3 to 3% by weight. The proportion of lubricant is particularly preferably from 0.5 to 2% by weight.

The proportion (in percent by weight based on the finished tablet) of individual active ingredient units in the rapidly disintegrating tablet is usually from 1 to 90% by weight. The proportion of individual active ingredient units is preferably up to 70% by weight, in particular from 10 to 50% by weight. The proportion is very particularly preferably from 15 to 25% by weight.

The proportion (in percent by weight based on the finished tablet) of binder can be up to 10% by weight, and it can preferably be up to 5% by weight.

If desired, one or more flavoring substances (e.g. flavors or sweeteners) can additionally be present in the rapidly disintegrating tablet. This makes it possible, for example, to achieve an improvement of the taste of the rapidly disintegrating tablet. These substances are added in conventional amounts.

The rapidly disintegrating tablet is produced by processes known to the skilled worker. The rapidly disintegrating tablet is preferably produced by

i) dry mixing of filler and/or disintegrant;

ii) production of granules of filler and binder and mixing of the granules with a disintegrant or

iii) dry granulation (briqueting or compacting) of one or more excipient components.

The individual active ingredient units are subsequently admixed to the mixtures obtained in i), ii) or iii) and then, if desired, flavors/flavoring substances and finally also one or more lubricants are admixed. The mixture obtained in this way can be compressed in a tablet press under conventional conditions.

Rapid disintegration of the tablet means according to the invention disintegration of the tablet in about 60 seconds or less when the tablet is subjected to a disintegration test as described in the European Pharmacopoeia (3rd edition, 1997) 2.9.1 disintegration time of tablets and capsules.

In the case of solutions and suspensions, suitable excipients are, in particular, those excipients which are normally used to produce solutions or suspensions. Particularly suitable according to the invention are excipients with which it is possible to produce a thickened base, such as thickeners. Examples of thickeners of the invention are xanthan, substituted celluloses, polyvinylpyrrolidone (polyvidone types), sheet silicates, alginates or alginic acids. Also possible if desired is a mixture of two or more different thickeners. The proportion of thickener depends on the desired viscosity or consistency intended for the solution or suspension ready for use. A solution or suspension with a viscosity of less than 500 mPa·s (determined with a rotational viscometer) is particularly preferred. The proportion of xanthan, based on the solution or suspension ready for use, is usually from 0.1 to 1% by weight. The proportion of substituted celluloses depends on the viscosity levels of the celluloses and is usually from 0.1 to 10% by weight based on the solution or suspension ready for use. Examples of substituted celluloses of the invention which may be mentioned are carboxymethylcellulose, ethylcellulose or methylcellulose or hydroxypropylcellulose. The proportion of polyvinylpyrrolidone (polyvidone types) is normally from 0.1 to 10% by weight based on the solution or suspension ready for use. Sheet silicates such as the Veegum or bentonites can be employed alone or in combination with water-soluble thickeners. The total proportion of thickener is then advantageously from 0.1 to 7% by weight based on the solution or suspension ready for use. Alginates and alginic acid are usually added in a proportion of from 0.1 to 10% by weight based on the solution or suspension ready for use. Further pharmaceutical excipients preferably employed are insoluble, crosslinked polyvinylpyrrolidone (crospovidones) and microcrystalline cellulose. It is observed in this case that a loose sediment forms and prevents agglomeration of the individual active ingredient units. The ratio of crospovidones to the individual active ingredient units is advantageously from 1:1 to 0.5:1 (based on weight). Microcrystalline cellulose, which is normally employed in a proportion of from 0.5 to 5% by weight based on the solution or suspension ready for use, is likewise suitable for this purpose. The proportion of individual active ingredient units in the solution or suspension ready for use is usually according to the invention from 1 to 20% by weight based on the solution or suspension ready for use, preferably 1 to 15% by weight and very preferably 5 to 10%. Water is preferably used as solvent or dispersant for the solution or suspension.

Other suitable excipients which may be present in the solution or suspension of the invention are, for example, flavoring substances (such as flavors and sweeteners), buffer substances, preservatives or else emulsifiers. Flavors are usually added in a proportion of from 0.05 to 1% by weight. Other flavoring substances by way of example are acids such as citric acid, sweeteners such as saccharin, aspartame, cyclamate sodium or maltol, which are added according to the desired result. Examples of emulsifiers are lecithins, sodium lauryl sulfate, Tweens® or Spans, which are normally added in a proportion of from 0.01 to 1% by weight. Preservatives such as benzoic acid, salts of benzoic acid, methyl 4-hydroxybenzoate, propyl 4-hydroxybenzoate, sorbic acid or salts thereof are preferably also added. The proportion depends on the preservative used and is normally from 0.1 to 4% by weight based on the solution or suspension ready for use.

The solution or suspension of the invention is produced by techniques known to the skilled worker. If a powder for reconstitution is to be produced, preferably a mixture of the individual active ingredient units with the thickener and, where appropriate, further excipients is produced. This powdered mixture for reconstitution is then mixed with a suitable amount of water immediately before administration. Solution or suspension ready for use is normally produced by introducing the individual active ingredient units into a dispersion of the thickener and, where appropriate, of additives in water or, alternatively, by introducing the thickener into a dispersion of the individual active ingredient units in water.

In a preferred embodiment, the invention relates to rapidly disintegrating tablets or solutions or suspension which comprise preparations of the invention with PDE inhibitors as active ingredients. Preferred PDE inhibitors in this case are roflumilast and pumafentrine.

The dosage forms of the invention can be employed for the treatment and prevention of all diseases which are regarded as treatable or preventable by use of the particular active ingredient. The dosage forms contain the particular active ingredient in the dose usual for treating the particular disease.

The production of dosage forms and preparations of the invention is described by way of example below. The following examples illustrate the invention in detail without restricting it.
